Description

InThis thisexample wayshows there is a possibilityhow to dohandle athe testRS232 communication via UART. After flashing both ports should send and adaptread todata workingfrom witheach externalother. devices. On the developer side there is an option to configure serial port parameters.

Default

Console settings:

• baud rate: 115200
• data bits: 8
• parity bits: 0
• stop bits: 1

output

After flashing, open serial port monitor and find out if the demo works properly.
